Solar Smart Energy in India: Current Landscape
India’s solar story has moved fast — from early pilot projects a decade ago to the backbone of the country’s renewable rollout today. The landscape in 2024–2025 is defined by three simultaneous shifts: rapid capacity additions, aggressive domestic manufacturing and policy support, and the early commercialization of integrated solar + storage (which turns variable solar into firm, dispatchable power). For corporate energy buyers and industrial leaders, these shifts change the economics and strategy of power procurement forever.
1) Scale today — the numbers that matter
India’s cumulative solar capacity (utility + rooftop + hybrid) crossed the 100 GW mark and, as of July 31, 2025, the MNRE reports ~119.02 GW of solar power installed, including roughly 90.99 GW of ground-mounted and 19.88 GW of grid-connected rooftop solar. This scale is transforming both grid dynamics and corporate purchasing options.
Rooftop adoption is accelerating too — H1 2025 saw a jump in rooftop installations compared with H1 2024, with industry trackers reporting multi-GW additions and an expanding distributed-solar market that’s increasingly attractive to manufacturing campuses.
2) Cost trajectory: solar and solar+storage are now highly competitive
The cost trajectory of solar smart energy has reached unprecedented levels of competitiveness. Solar auction tariffs in India remain extremely low, with record bids dipping into the low ₹2–₹3 per kWh range for utility-scale solar. Bundled solar+storage auctions are also discovering competitive “pack” prices. In 2024, the lowest tariffs were around ₹2.15/kWh, while recent solar+4-hour storage tenders produced discovered tariffs near ₹3.3/kWh (pack). These levels make solar smart energy, providing 24×7 clean power, a commercially viable alternative to conventional thermal power for many industrial contracts. Such price signals are reshaping long-term corporate power procurement strategies.
3) Domestic manufacturing: PLI is reshaping supply chains
India’s Production Linked Incentive (PLI) schemes and industrial policies have driven a steep increase in domestic PV manufacturing capacity. Recent reports indicate that module manufacturing capacity is expanding rapidly, with significant new lines announced under the PLI program. For businesses, this growth in domestic manufacturing enhances the security of solar smart energy supply, shortens lead times, and reduces exposure to global trade uncertainties, making industrial adoption smoother and more predictable.
4) Storage: still early but scaling quickly
Battery Energy Storage System (BESS) deployment in India is accelerating from a modest base. Installations grew from a few dozen MWh in 2022–2023 to several hundred MWh in 2024, with large GWh-scale pipelines tied to solar projects underway. While grid integration and implementation speed remain challenges, storage is clearly moving from pilot stages to mainstream adoption. When paired with PV, solar smart energy solutions with storage deliver firm, dispatchable power for industrial users, unlocking the full potential of renewable energy.
5) Policy & market enablers — a favourable regulatory ecosystem
Corporate buyers benefit from a favourable regulatory ecosystem that supports solar smart energy deployment. Key policy instruments include Renewable Purchase Obligations (RPOs), net-metering, open-access regulations for captive procurement, accelerated depreciation, and state-level hybrid park and RTC renewable tenders. The combination of central and state-level support creates multiple pathways for manufacturers to design customized solar smart energy solutions that meet both operational and sustainability objectives.
6) Emerging product-market fit: from captive roofs to RTC PPAs
The industrial adoption of solar smart energy has evolved far beyond rooftop installations. Today, businesses can choose from captive rooftops, ground-mounted farms, open-access PPAs, corporate offtake via SECI/state auctions, and solar+storage bundles capable of delivering firm, multi-hour power. These options allow manufacturers to reduce energy costs, lock in predictable tariffs, minimize carbon footprints, and improve resilience against grid outages and fossil fuel price volatility.
7) Technology & system intelligence — the “smart” in Solar Smart Energy
Solar smart energy is not just about panels and inverters—it’s about intelligent, digitally enabled systems. IoT monitoring, AI-driven performance analytics, advanced O&M, demand-side scheduling, and grid-interactive storage dispatch all combine to maximize yield, minimize downtime, and make energy predictable and manageable. Factories adopting solar smart energy can even participate in energy markets, selling surplus power or providing ancillary services, turning intermittent solar generation into a reliable business asset.
8) Challenges on the horizon (and how industry can mitigate them)
- Transmission & curtailment risk: With rapid capacity additions, grid expansion and flexibility lag in places — requiring careful siting and grid studies. (MNRE and state utilities are actively addressing these.)
- Storage rollout pace vs. pipeline: Large BESS pipelines exist, but a minority are operational today; execution and supply-chain hurdles remain. Contractors and offtakers should stress-test timelines and include performance milestones.
- Quality control & warranties: Rapid local manufacturing means variable supplier quality; rigorous procurement specs and EPC oversight are essential.
- Policy heterogeneity across states: Rules for net metering, open access, and interconnection vary — legal and regulatory diligence is required before project rollout.
9) Opportunities for manufacturers & decision-makers — what to act on now
- Capitalize on captive rooftops & brownfield land: immediate OPEX reductions and fast paybacks.
- Consider bundled solar + storage PPAs for resiliency and for meeting internal sustainability targets with firm power.
- Leverage PLI and local supply chains to de-risk procurement and shorten project lead times.
- Deploy smart O&M & analytics to maximize yield and extend asset life; this improves ROI and reduces unplanned downtime.
10) Near-term outlook (12–36 months) — what to expect
Expect continued robust capacity additions in solar smart energy, with a growing share of rooftop and distributed solar projects. More tenders are now combining storage with solar, and domestic module and cell manufacturing under PLI will continue to scale rapidly. Operational BESS capacity is set to increase from today’s hundreds of MWh to multiple GWh as projects move from award to commissioning, unlocking truly firm and reliable solar smart energy solutions for industrial consumers over the next 2–3 years.
Key Benefits of Solar Smart Energy in India
The adoption of Solar Smart Energy India brings several transformative advantages:
1. Cost Savings
Solar smart energy offers an economically compelling solution for industries, with tariffs ranging from ₹2.5 to ₹3 per unit, often making it cheaper than coal or conventional grid power. Some recent auctions have even recorded tariffs as low as ₹2.15/kWh. Rooftop solar smart energy systems typically deliver a return on investment (ROI) within 3–5 years, providing nearly free electricity for over two decades. The inherent price stability of sunlight, unlike volatile fossil fuel markets, is further enhanced through Power Purchase Agreements (PPAs), which allow industries to lock in predictable tariffs for 15–25 years.

Solar Smart Energy India – Challenges
1. Transmission & Grid Constraints
One of the biggest barriers to solar expansion in India is insufficient transmission infrastructure. In states like Rajasthan and Gujarat, where solar potential is highest, delays in building new substations and transmission corridors have led to curtailment of generated power — in some cases, up to 25% of solar output goes wasted. For industries investing in solar through open access or captive models, this means lower utilization of installed capacity and financial losses. Strengthening the grid and speeding up transmission projects is critical for long-term reliability.
2. High Upfront Costs & Storage Economics
While solar costs have dropped significantly, solar + storage systems — essential for round-the-clock reliability — remain expensive. Adding batteries can increase the total system cost by 40–70%. Lithium-ion and advanced batteries are still not cost-effective at scale for many industrial users, making payback periods longer. For manufacturing units that run 24×7, the economics of solar can be challenging without government incentives or innovative financing.
3. Policy & Regulatory Uncertainty
India’s solar policies are ambitious, but they vary widely by state and are subject to frequent changes. Rules around net metering, open access charges, wheeling charges, and approved lists of models (ALMM) shift often, leaving investors and industries uncertain. For a business making long-term energy decisions, this lack of stability creates hesitation. What looks profitable today could change tomorrow with a new tariff order.
4. Financing & Discom Risks
The cost of capital in India is relatively high compared to developed markets, raising project costs. While CAPEX projects offer high ROI, many industries prefer OPEX/PPA models, but these depend on financing and bankability. Additionally, financially stressed Discoms (distribution companies) often delay payments or attempt to renegotiate power purchase agreements (PPAs). This creates revenue risk for solar developers and indirectly impacts industrial buyers of solar power.
Government Policies and Subsidies Supporting Smart Solar in India
1. Production Linked Incentive (PLI) Scheme for High
The initiative aims to establish gigawatt (GW)-scale domestic manufacturing capacity for high-efficiency solar photovoltaic (PV) modules. This undertaking is designed to diminish reliance on imported solar hardware, enhance the efficiency of solar modules, and fortify the national solar hardware industry. The second tranche of the scheme allocates ₹19,500 crore to support approximately 39,600 megawatts (MW) of manufacturing capacity distributed among various manufacturers. Financial disbursements are scheduled over a five-year period subsequent to the commissioning of these manufacturing plants. Anticipated key outcomes include a significant expansion of domestic module production, the creation of hundreds of thousands of direct and indirect jobs, an improvement in the overall quality of solar modules, and the development of export capabilities.
2. Approved List of Models & Manufacturers (ALMM)
The Approved List of Models and Manufacturers (ALMM) is a government regulation that designates specific solar modules, and eventually solar cells and wafers from approved sources, as eligible for government-tied projects, net-metering, open access, and other subsidy-linked initiatives. Beginning June 1, 2026, projects within these categories must utilize modules containing solar cells listed under ALMM List-II, with exemptions available for projects bid prior to relevant deadlines.
A proposed amendment seeks to extend ALMM to include solar wafers from June 1, 2028, thereby covering the upstream supply chain, encompassing modules, cells, and wafers under domestic verification processes. The government has implemented easing measures, such as providing grace periods after list publications and offering exemptions for certain project categories or bids submitted by specified dates, to facilitate compliance and mitigate abrupt market impacts.
3. Tax, GST & Import/Custom Duty Adjustments
The government has reduced the Goods and Services Tax (GST) on solar modules and certain solar equipment to decrease capital expenditure (CAPEX) for industry adopters. While various tax and duty policies affecting solar equipment are subject to change, modules and associated goods receive preferential treatment under specific schemes. Import duties and restrictions, especially for components that are not manufactured domestically or do not comply with domestic content or approved list requirements, are implemented to foster backward integration and promote domestic manufacturing. The Approved List of Manufacturers and Models (ALMM) and Production Linked Incentives (PLI) schemes are instrumental in supporting these objectives.
4. Policy Support for Net-Metering, Open Access & Captive / Behind-the-Meter Solar
Many states offer net metering or net-billing, a policy that credits customers for excess solar power exported to the grid, thereby improving the financial viability of solar and storage systems, particularly rooftop installations. Open access policies permit large industrial and commercial users to purchase solar power from offsite solar farms or collective solar projects through Power Purchase Agreements (PPAs), offering an alternative to solely relying on grid electricity and providing flexibility for sourcing more affordable and cleaner energy. While behind-the-meter installations, where onsite generation is used for self-consumption, are increasingly supported through subsidy and tender programs, their implementation varies across different states.
Future of Solar Smart Energy in India
India’s solar smart energy sector is poised for significant growth, driven by ambitious renewable energy targets and technological advancements. By 2030, the country aims for 500 GW of non-fossil fuel capacity, with solar expected to contribute substantially, reaching 280–320 GW and positioning India as a global leader.

Key trends shaping this future include the rise of solar-plus-storage solutions, which are crucial for ensuring round-the-clock power availability and grid stability as solar penetration increases. Falling battery costs and hybrid projects are expected to accelerate this transformation. Technological integration of artificial intelligence, IoT, and data-driven systems will lead to smarter, more efficient solar operations through predictive maintenance and real-time monitoring, while smart grids will enable dynamic energy trading.
India is also prioritizing self-reliance in solar manufacturing through initiatives like the Production Linked Incentive (PLI) scheme, aiming for substantial domestic module and cell manufacturing capacity by 2030. This will reduce import reliance and secure the supply chain. For energy-intensive sectors, adopting solar smart energy can cut energy costs by 30–50% through captive plants, open access, or rooftop installations, simultaneously strengthening ESG credentials and enhancing competitiveness in green export markets.
Government policies, including net metering, open access reforms, tax benefits, and accelerated depreciation, are making solar adoption financially attractive. Furthermore, frameworks for carbon credits, green financing, and mandates for storage and smart meters will accelerate the transition. Ultimately, investing in solar smart energy offers Indian industries a strategic imperative for long-term growth, providing lower costs, stronger compliance, and a competitive edge in global markets.
